What is ROMS?

[robertson]

The Regional Ocean Model System (ROMS) is a free-surface, hydrostatic, primitive equation ocean model that uses stretched, terrain-following coordinates in the vertical and orthogonal curvilinear coordinates in the horizontal. Initially, it was based on the S-coordinate Rutgers University Model (SCRUM) described by Song and Haidvogel (1994). ROMS was completely rewritten to improve both its numerics and efficiency in single and multi-threaded computer architectures. It also was expanded to include a variety of new features including:

• 1. high-order advection schemes
  2. accurate pressure gradient algorithms
  3. several subgrid-scale parameterizations
  4. atmospheric, oceanic, and benthic boundary layers
  5. biological modules
  6. radiation boundary conditions
  7. data assimilation.
